same part number or with an equivalent part if replacement part of lesser quality or substitute design.
Torque values must be used as specified during reassembly to assure proper retention of all parts.
There is to be no welding as it may result in extensive damage and weakening of the metal.

General Description
The ABS (Antilock Brake System) is a system to prevent each wheel to lock during hard braking or braking on a
slippery road by controlling the fluid pressure from master cylinder to each brake (either brake caliper or wheel
cylinder).
The ABS of this vehicle monitors all four wheels (four sensors) and controls all four wheels when the system is
active.
The component parts of this ABS includes following parts in addition to those of the conventional brake system.
Wheel speed sensor senses revolution speed of each wheel and sends outputs to ABS control module.
In this ABS, ABS hydraulic unit (actuator assembly), ABS control module, pump motor transistor and fail-
safe transistor are combined as one component.
ABS control module sends operation signal to ABS hydraulic unit to control fluid pressure applied to each
wheel cylinder based on signal from each wheel speed sensor so as to prevent wheel from locking.
ABS hydraulic unit operates according to signal from ABS control module and controls fluid pressure applied
to wheel cylinder of each of 4 wheels.
Fail-safe transistor which supplies power to solenoid valve in ABS hydraulic unit.
Pump motor transistor supplies power to pump motor in ABS hydraulic unit.
“ABS” warning lamp lights to inform abnormality when system fails to operate properly.
G sensor which detects body deceleration speed.

ABS Control Module
Self-diagnosis function
ABS control module diagnoses conditions of the system compo-
nent parts (whether or not there is any abnormality) all the time
and indicates the results (warning of abnormality occurrence and
DTC) through the “ABS” warning lamp as described below.
1) When ignition switch is turned ON, “ABS” warning lights for 2
seconds to check its bulb and circuit.
2) When no abnormality has been detected (the system is in
good condition), “ABS” warning lamp turns OFF after 2 sec-
onds.
3) When an abnormality in the system is detected, “ABS” warn-
ing lamp lights and the area where that abnormality lies is
stored in the memory in ABS control module.
4) When Diag. switch terminal of monitor connector is
grounded, the abnormal area is output as DTC.
For procedure to clear all DTC’s, refer to the item “Diagnostic
Trouble Code (DTC) Clearance” in this section.
Fail-safe function
When an abnormality occurs (an abnormal DTC is detected),
ABS control module turns OFF the fail-safe transistor which sup-
plies power to ABS hydraulic unit. Thus, with ABS not operating,
brakes function just like the brake system of the vehicle without

Diagnosis
To ensure that the trouble diagnosis is done accurately and smoothly, observe “Precautions in Diagnosing Trou-
bles” and follow “ABS Diagnostic Flow Table”.
Precaution in Diagnosing Troubles
If the vehicles was operated in any of the following ways, “ABS” warning lamp may light momentarily but this
does not indicate anything abnormal in ABS.
–The vehicle was driven with parking brake pulled.
–The vehicle was driven with brake dragging.
–The vehicle was stuck in mud, sand, etc.
–Wheel spin occurred while driving.
–Wheel(s) was rotated while the vehicle was jacked up.
Be sure to read “Precautions for Electronic Circuit Service” in Section 0A before inspection and observe
what is written there.
Be sure to use the trouble diagnosis procedure as described in the flow table. Failure to follow the flow table
may result in incorrect diagnosis. Some other diag. trouble code may be stored by mistake in the memory of
ABS control module during inspection.
ABS Diagnostic Flow Table
Refer to the following for the details of each step.
Step Action Yes No
1 Perform customer complaint analysis, problem symptom confir-
mation and diagnostic trouble code check record and clear-
ance.
Is there any trouble code?Go to Step 2. Go to Step 5.
2 Perform driving test.
Is trouble symptom identified?Go to Step 3. Go to Step 6.
3 Check diagnostic trouble code.
Is it malfunction code?Go to Step 4. Go to Step 5.
4 Inspect and repair referring to applicable diagnostic trouble
code table in this section. Then perform final confirmation test
after clearing diagnostic trouble code.
Is trouble recur?Go to Step 7. End.
5 Inspect and repair referring to “Diagnosis Table” in Section 5.
Then perform final confirmation test after clearing diagnostic
trouble code.
Is trouble recur?Go to Step 7. End.
6 Check for intermittent problems referring to “Intermittent and
Poor Connection” in Section 0A and related circuit of trouble
code recorded in Step 3. Then perform final confirmation test
after clearing diagnostic trouble code.
Is trouble recur?Go to Step 7. End.
7 Perform diagnostic trouble code check record and clearance.
Is there any trouble code?Go to Step 4. Go to Step 5.

1) MALFUNCTION ANALYSIS
a) Customer Complaint Analysis
Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a questionnaire form as shown below will facilitate collecting information to
the point required for proper analysis and diagnosis.
CUSTOMER QUESTIONNAIRE (EXAMPLE)
b) Problem Symptom Confirmation
Check if what the customer claimed in “Customer Questionnaire” is actually found in the vehicle and if the
symptom is found, determine whether it is identified as a failure. (This step should be shared with the cus-
tomer if possible.) When “ABS” warning lamp is not operating correctly, proceed to “Diagnostic Flow Table-
A, B or C” in this section.
c) Diagnostic Trouble Code (DTC) Check, Record and Clearance
Perform “Diagnostic Trouble Code Check” procedure in this section, record it and then clear it referring to
“Diagnostic Trouble Code Clearance” in this section.
If the malfunction DTC which was once displayed and then cleared cannot be detected (indicated) again
when the ignition switch is turned ON, attempt to diagnose the trouble based on the DTC recorded in this
step may mislead the diagnosis or make diagnosing difficult. Proceed to Step 2 to check ABS control mod-
ule for proper self-diagnosis function.
If the malfunction DTC which was once displayed and then cleared can be detected (indicated) again when
ignition switch is turned ON, proceed to Step 3.

2) DRIVING TEST
Test drive the vehicle at 40 km/h for more than a minute and check if any trouble symptom (such as abnor-
mal lighting of “ABS” warning lamp) exists.
If the malfunction DTC is confirmed again at ignition switch ON, driving test as described in above is not nec-
essary. Proceed to Step 3.
3) DIAGNOSTIC TROUBLE CODE CHECK
Recheck diagnostic trouble code referring to “DTC Check” in this section.
4) DIAGNOSTIC TROUBLE CODE FLOW TABLE
According to Diagnostic Flow Table for the diagnostic trouble code confirmed in Step 3, locate the cause of
the trouble, namely in a sensor, switch, wire harness, connector, actuator, ABS control module or other part
and repair or replace faulty parts.
5)“DIAGNOSIS TABLE” IN SECTION 5
Check the parts or system suspected as a possible cause referring to “Diagnosis Table” in Section 5 and
based on symptoms appearing on the vehicle (symptoms obtained through Step 1)-a, 1)-b and 2) and repair
or replace faulty parts, if any.
6) CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to
Intermittent Trouble in Section 0A and related circuit of trouble code recorded in Step 1)-c.
7) FINAL CONFIRMATION TEST
Confirm that the problem symptom has gone and the ABS is free from any abnormal conditions. If what has
been repaired is related to the malfunction DTC, clear the DTC once and perform test driving and confirm
that a normal code is indicated.
